BANDING MECHANISM Application May 31, 1933, Serial No. 673,765

3 Claims.

In the decoration of ceramic ware, such as china and the like, byplacing bands of coloring material thereon, it is usual to place thearticle on the center of a rotatably mounted table and 5 spin the tableandsupported article while ap plying to the article a brush carrying thecoloring material. In such method some difficulty is encountered incentering the article and the method itself is not such as will permitof a high rate of output.

The present invention relates to the application of bands of coloringmaterial to glassware, china, or other ceramic ware, and has for itsprimary object to provide a mechanism which will support the articles tobe decorated in a centered position for spinning and yet which willadmit of rapid manipulation so as to greatly expedite the production ofdecorated articles.

A further object of the invention consists in the provision of a clampfor the articles which may be easily and quickly operated either tosecure or release the articles being operated upon.

Another object of the invention consists of an M adjustable mechanismwhich will permit the articles to be spun on a horizontal axis, avertical axis or any intermediate position most suitable to theparticular shape of the articles being operated upon.

Other objects and advantages of the invention will be apparent from thefollowing description when taken in connection with the accompanyingdrawings, in which,

Figure 1 is a perspective view of the complete apparatus as adjusted foruse in placing bands on cups or similar receptacles.

Figure 2 is a fragmentary elevational view showing the arm rest in use.

Figure 3 is a fragmentary elevational view partly in section showing theclamping mechanism in detail.

Figure 4 is a perspective view of the mechanism shown in Figures 1, 2and 3 but with the apparatus arranged for decorating a different type ofarticles, such as saucers, plates, etc.

Figure 5 is a view similar to Figure 3 showing a slightly modifiedconstruction of clamp, and

Figure 6 is a detail view showing the manner of applying bands toarticles mounted on the apparatus as arranged in Figure 4.

Referring to the drawings in greater detail and especially to Figures 1,2 and 3, the numeral I indicates a base member provided with lateralextensions 2 of sufficient extent to firmly support the apparatusmounted thereon. Extendi s pw y from the base I is a socket member 3provided with a set screw 4 for adjustably securing a rod 5 on which theapparatus is pivotally mounted.

The upper end of rod 5 is provided with a hinge knuckle 6 having anupturned edge I. A 5 complemental hinge knuckle 8 is pivotally connectedto knuckle 6 by means of a bolt 9, and the design of the knuckles issuchthat they may have a relative movement of 90 but no more. The knucklest8 maybe locked against pivotal 10 movement by tightening up on the bolt9. The upper end of the hinge member 8 is provided with a threadedportion l!) to which is secured a table ll; a clamping nut I2 serving tolock the table in position. By the hinge construction it 15 will be seenthat the table may be adjusted from horizontal to vertical position orto any position intermediate these two extremes. Moreover, by looseningthe nut t2 the table may be rotatably adjusted about the pin I0.

Fixedlymounted on the table II, in either of the apertures I3, is aheadstock including a pedestal M which is secured in position by meansof nuts I5. A double bearing I6 is fixed to the upper end of pedestal l4and has mounted therein a shaft IT. The bearings l6 are perferably ofthe radial type to permit free rotary movement of the shaft at alltimes. Fixed on the end of shaft ll is a disc I8 forming a chuck or faceplate for the reception of the base of the article being operated upon.This member I8 is preferably grooved as at i9 to provide a centeringmeans for the articles.

Keyed to the shaft H is a cylindrical member 20 which is knurled on itsouter surface as indicated by the numeral 2!. This element 20 serves asa gripping means for the fingers of the operator in spinning the shaftI1 and also, by reason of its weight, cooperates with the plate 18 toprovide the necessary inertia for the shaft I1.

The tailstock of the mechanism is slidably mounted in a longitudinalslot 22 formed in the table II, which slot may be closed at its outerend by a crossbar 23. A crosshead 24 is provided with longitudinalgrooves which receive the edges of the table bounding the slot 22, and avertical opening through the crosshead receives the lower end of thetailstock pedestal 25. A set screw 26 provides the necessary verticaladjustment of the tailstock. The upper end of the element 25 is bentinto horizontal positions as indicated by numeral 21, and has rotatablymounted thereon as by bearing 28 a head or mandrel 29. The bearing forthe mandrel 29 is preferably of the self-aligning type to permit thehead to automatchain has one end anchored to the cross-head 24asindicated at 32' and then passes over guide pulleys 33 and 34 and hasits opposite end secured to an eye 35 fixed on an operating pedal 36.The end of the chain is provided with a hook 31 adapted to engage in anappropriate link thereof to provide the necessary adjustment for variouspositions of the table II. By pressing the foot uponthe pedal 36 it willbe obvious that the tailstock 21 is withdrawn against the tension ofsprings 30 to allow the removal of a'decorated article and thesubstitution of an article to be decorated. V

7 As will be readily understood, the band of col oring material isapplied to the article by spinning the shaft IT with the article clampedthereon, and then holding the tipof the brush bearing the color againstthe article. Obviously some means forsteadying the arm of the operatoris desirable in order to accurately position the band of color on theware and for this purpose an arm rest consisting of an elongated plate38 is provided. The plate 38 carries a bolt-receiving eye 39 onits'underside which cooperates with a similar eye 40 formed on a rod Mwhich is adjustably mounted in a sleeve 42 as by means of a setscrew 43.A bolt 44 passing through the eyes 39 and 40 provides for angularadjustment of the arm rest 38 while the slotted bracket 45 and bolt 46provide for its bodily adjustment with respect to the table I I. 7

A mixing tile or palette for the paint or other coloring material beingapplied to the ware is indicated by the numeral 41. This member 41 ismounted on an arm 48, and the latter is pivoted to the table II asindicated by numeral 49.

With the apparatus as thus far described and as shown in Figures 1, 2and 3, the arm rest and palette are adjusted to substantially thepositions indicated, and the tailstock operated in the manner heretoforedescribed to permit a cup or other similar receptacle to be centered andclamped between the headstock and tailstock. The bearings in thesemembers cause them to automatically adjust themselves to variations inthe ware or elsewhere. The operator now spins the ware by applying aspinning movement to the 'member ZIl, and with his arm preferablyresting on the plate 38 applies the tip of the brush to the article atthe desired distance from the end thereof. The spinning of the ware willof course cause the band or stripe to be applied around its entirecircumference in the plane selected.

If it is desired to place a band on a more or less fiat article such asa saucer the operation is greatly facilitated if the article isrotatedin a more or less horizontal'plane. It is primarily for thisreason that some of the adjustments heretofore referred to have beenembodied in the invention.

For instance, by referring to Figure 4 it will be seen that the hinge 68has been operated through 90 to bring the table I I to vertical positionand the table has been swung angularly about of the operator. Also, thebracket 45 is swung, to a more suitable angular position so as to betteradapt the arm rest 38 to the Work; and in this connection it is to benoted that a rod 50 provided with a pivoted extension 5| is mounted inthe 5 sleeve 42 in lieu of the rod 4! shown in Figure 1, thus providinga more flexible adjustment for the arm rest. And again, the arm 48 forthe palette 41 is removed from its pin 49 and connected by a universaljoint 52 with an arm 53 which is secured to the table by a bolt 54 inaperture 55 (Figure 1).

r In this arrangement of the apparatus for use with substantially fiatware the change of the table II from horizontal to vertical positionproduces a certain amount of slack in the operating cable 32 of thetailstock, and in order to make the necessary adjustment the cable isdrawn furticle is presented to the operator in a position best suited tothe application of the brush. v

In applying bands to articles provided with large handles or in whichfor other reasons the weight is not equally distributed it is desirableto provide some means to insure a smooth spinning of the article if theband is to be properly applied, and a' modified construction for thispurpose is shown in Figure 5. In this'form of the invention the shaft 60of the headstock is provided with a suitable counter-weight 6| which isdetachably connected to the shaft by a'clamp 62. The article to bebanded will of course be mounted on the headstock with the handlediametrically opposed to the counter-weight, to insure a smooth turningof the shaft.

This modified form of headstock includes a baseplate 63 provided with adownwardly-extend ing rod 64 which is adjustably secured in thecrosshead 24 by a set screw 65. The shaft 60 is mounted in a pair ofradial bearings 66 fixed on the end of a vertical post 61 which has itslower end secured in a slot 68 in the base plate. A knurled drum 69 issecured to the outer end of shaft 60 for operating the same, and theinner end of the shaft, is provided with a face plate I0 and rubbercushion II for engaging the base of the article being operated upon.

From the above description and the accompanying drawings it will beapparent that an efficient and simple apparatus for centrally supportingand rotating ware during the banding operation has been provided; thatthe device may be readily adapted to the decoration of either flat orcylindrical ware as desired; that the articles may be released orclamped by movement of the parting from the spirit of the invention, andall such changes and modifications are intended to be included withinthe scope of the appended.
